In order to avoid shading between arrays, the array spacing of solar cell modules should not be less than D, D=0.707H/tan (arcsin (0.648cos-0.399sin)), where, when the geographic latitude (positive in the northern hemisphere and negative in the southern hemisphere), H is the height difference between the highest point in the front row of the array and the lowest position in the rear row of the array.
According to the above formula, D=5025mm is obtained, and the array spacing
